HIDALGO RODRIGUEZ, Roxana; CASTELLANOS FERNANDEZ, Vivian; CHIROLES DESPAIGNE, Sonia  and  VILLAVICENCIO BETANCOURT, Odalys. Estudio químico-microbiológico comparativo de dos soluciones propuestas para la desinfección de endoscopios. Rev Cubana Hig Epidemiol [online]. 2000, vol.38, n.3, pp. 210-214. ISSN 1561-3003.

From the chemical-microbiological point of view the germicide activity of a solution proposed for the desinfection of endoscopy instruments (7 % hydrogen peroxide) was evaluated. 2 % glutaraldehyde was taken as a reference solution. The solutions were assayed at the concentrations proposed by the manufacturers for 20 minutes, period of time indicated by them. As a result of the microbiological assessment it was observed that 7 % hydrogen peroxide solution gives 100 % inhibition of microbial colonies forming units compared with 2 % glutaraldehyde solution which offers 100 % inhibition. The chemical assays of materials compatibility in which corrosion tests and confrontantion of the solutions to different polymers and to 2 classes of crystal developed were satisfactory for the solutions proposed.
